Running Your Engine While You're Parked; Locking Rear Axle (If Equipped) - GMC 1998 Savana Van Owner's Manual

Running Your Engine While
You're Parked
It's better not to park with the engine running. But if
ever you have to, here are some things to know.
t -
Idling the engine with the
air system control off
could allow dangerous exhaust into your vehicle
(see
the earlier Caution under "Engine Exhaust").
I
Also, idling in
a
closed-in place can let deadly
carbon monoxide
(CO)
into
your
vehicle even
if the fan switch is at the highest setting. One
place this can happen is a garage. Exhaust
--
with
CO
--
can come in easily. NEVER park in
a
garage with the engine running.
Another closed-in place can be a blizzard.
(See "Blizzard" in the Index.)
It can be dangerous to get out of
yvur
vehicle if
the shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you've left the
engine running, the vehicle can move suddenly.
You or others could be injured. To
be sure your
vehicle won't move, even when you're
on
fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle won't
move. See "Shifting Into PARK (P)" in the Index.
If you're pulling a trailer, see "Towing a Trailer" in
the Index.
Locking Rear Axle ( I f Equipped)
If you have this feature, your locking rear axle can give
you additional traction on snow, mud, ice, sand or
gravel. It works like a standard axle most of the time,
but when one of the rear wheels has no traction and the
other does, this feature will allow
the
wheel with
traction to move the vehicle.
